SPECIFICATION forming part of Letters Patent No. 717,967, dated January 6, 1903.

Application ined `.April 1 s, 1902.`

To all whom it may oon/cern,.-

Beit known that I, EDWARD S. BUCKLAND, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented new and useful Improvements in Fire-Extinguishers, of which the following is a specification.

This invention relates to fire-extinguishers of that class embodying alkali and acid receptacles wherein the acid is commiugled with the alkali when it is desired to operate the extinguisher; and the purpose of the present improvementis to provide simple and effective'meaus for supporting and breaking or crushing the acid bottle or receptacle in a positive and reliable manner.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed. A

In the drawings, Figure 1 is a transverse vertical section of a fire-extinguisher embodying the features of the invention. Fig. 2 is a sectional elevation of the cap and acid-bottle support and crushing device forming the essential features of the improvement. Fig.

3 is a horizontal section taken in the plane l of the line 3 3 of Fig. 1 to show the acid-bottle holder or cage and the movable section or element thereof. Fig. 4 is atransverse vertical section of the acid bottle or receptacle.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates a tank, of cylindrical shape, which is preferably formed of copper and has a convex bottom 2 and a top 3 with an upstanding screw-threaded neck 4, surrounding an inlet-opening extending through the top 3, and diagonally disposed within the tank is an outlet-pipe 5, having a lower closed end and a plurality of perforations 6 adjacent said end, the upper end of the pipe being rmly held by a plug 7, fitted in the topV and having a flexible pipe 8 secured thereto andr of any suitable length. The pipe 5 is diagonally disposed to bring the lower end thereof in central position in the interior of the tank, so as to be more effective in fully exhausting the contents of said tank. This thorough exhaust of the contents of the tank is materially aided by the provision of semina 103,596. or@ model.)

l the convex bottom 2, and a further object in disposing the pipe 5 diagonally within the interior of the tank is to have the upper end thereof close to the periphery of the top 3 for obvious reasons@A Removably tted on the neck 4 is a cap 9, having a T-shaped handle 10 with a central bore 1l extending vertically therethrough. Secured to the cap 9 is a cage or holder 12, comprising a lower yoke 13, having opposite side bars connected by a lower horizontal bar, the upper ends of the side bars being secured to an intermediate clasp 14, from which arms 15 vertically extend to the inner portion of the cap 9. The arms 15 are practically continuations of the side bars of the yoke and serve to suspend the entire cage from the cap 9, the width of the cage being less than the diameter of the inlet-openingsurrounded by the neck 4, so as to be freely movable through said opening. The clasp 14 comprises a stationary segment 16 and a hinged segment 17, the latter having a spring-catch 18 on its free end, which is adapted to snap over a stud 19, projecting outwardly from the one `end of the segment 16. The inner edges of the segments 16 and 17 are cut away to form a central opening through the clasp, said edges at diametrically opposite central points having inward projections 2O to contract the central portion of the opening through the clasp for a purpose which will be presently explained.

Within the bore 11 of the handle 10 is a `plunger 21, having a head 22 on its upper end and a bridge 23 at its lower extremity comprising opposite arms 24,which have their terminals 25 reduced and shaped similarly to wedges. Between the head 22 and the upper edge of the handle 11 a spring 26 surrounds the plunger 21 to hold the latter and the bridge at the lower end thereof in a normal elevated position, the upward movement of the plunger being limited by a collar 27,

4which is adapted to contact with the lower side of the cap, through which the bore 11 also extends. The arms 24 areadapted to move downwardly through the opening of the clasp 14 in planes at right angles to the positions of the projections 20. The cage 12 has an acid bottle or receptacle 28 fitted therein by first opening the movable segment 17, and

IOO

after the said bottle is placed in the cage the segment 17 is closed and locked shut by the spring-catch 18, the projections 2O extending over the upper or top portion of the bottle and operating to hold the latter in the cage. The wedge-shaped ends 25 of the arm 24 bear upon the top of the bottle 28, and the latter is formed with a central upwardly-projecting closed neck 29, which is sealed after the acid has been placed within the bottle, it being understood that the bottle will be formed of glass. When the bottle is located in the cage, the closed neck extends upwardly into the opening of the bridge 23 between the arms 24.

The alkali and acid used will be similar to those ordinarily employed for this purpose and operating, when commingled, to force the contents of the tank outwardly through the pipe 5 for application to a fire through the medium of the flexible tube 8,which will be supplied with a suitable nozzle. The alkali is first placed in the tank by removing the cap 9, and before applying the cap the acid-bottle 28 is disposed and locked in the cage l2 and the said cap 9 then applied and the acid-bottle located within the upper portion of the tank above the top surface of the alkali. To use the extinguisher, downward pressure is exerted on the plunger by means of a sharp blow delivered on the head 22, and the arms 24.- crush or break the tcp portion of the bottle, thereby liberatingr the acid and permitting it to mingle with lhe alkali. The top of the bottle is not only broken, but the side portions will also be split, and by this means the entire bottle will become demolished, so that nothing remains of it but the bottom. 29 projects upwardly into the opening of the bridge, and in forcing the said neck downwardly into the body of the bottle, lateral pressure is exerted on the side of the latter, with the result that a thorough breaking up of the bottle ensues, as before set forth. It will be understood that the contents of the tank can be conveniently applied through the medium of the exible tube and its nozzle in the form of a spray, which may be regulated as desired by the use of any of the well-known forms or a particular shape of nozzle. The extinguisher after use may be readily recharged, and in applying and re- This is due to the fact that the neck' moving the cap 9 the T-shaped handle will provide convenient grasping means. It is also proposed to form the cage and plunger with its bridge of suitable metal and to supply the acid-bottles in the form set forth in quantities, so that they can-be readily obtained for the purpose of recharging4 the extinguisher.

By the arrangement of the acid-bottle and the means for breaking the same, as heretofore described, said bottle is absolutely sure to spill its contents, because, if not wholly demolished, it will fall from the cage, and thereby cause the contents thereof to become effectively commingled with the alkali solution.

Having thus fully described the invention, what is claimed as new isl. In a fire-extinguisher, the combination of a tank adapted to contain alkali, and provided with an opening in the upper end thereof, a cap removably fitted over the said opening and having a depending cage with a horizontally-disposed locking-clasp comprising a hinged section, an acid-bottle with an upwardly-projecting closed neck adapted to extend through the clasp, and a plunger vertically movable through the cap and provided with a lower bridge having opposite members spanning diametrically opposite portions of the neck to crush the latter and the body of the bottle below.

2. In a re-extinguisher, the combination of a tank adapted to contain an alkali, a removable cap for the tank havingadepending cage with an upper horizontally disposed clasp comprising hinged members, a springactuated plunger extending through the cap and having lower diametrically disposed breaking members, and an acid-bottle with an upwardly-projecting closed neck extending through the opening in the clasp, the latter being of less dimensions than lthe body of the bottle, and the neck of the acid-bottle being adapted to be diametrically spanned by the members on the lower end of the plunger.

In testimony whereof I aflix my signature in presence of two witnesses.

EDWARD S. BUCKLAND.
